Pulsating heat pipes are cooling devices that are partially filled with working fluid. Working fluid thermophysical properties affect the thermal performance of pulsating heat pipes. In this research, the effect of adding a Triton X-100 surfactant to pure water and using the mixture as a working fluid is investigated experimentally. The results indicate that adding surfactant leads to improvement in the thermal performance of the pulsating heat pipe. In particular, the maximum of the thermal resistance improvement is about 61%, which is attributed to 0.01% surfactant concentration. Higher heat transfer ability is attributed to lower surface tension and the contact angle of the mixture compared with pure water. The startup performance happens at a lower temperature by using Triton X-100 and a water solution (the surfactant solution reduces the startup required temperature by approximately 50% in comparison to the startup temperature of pure water). An optimal concentration for Triton X-100 in water exists as a working fluid in the pulsating heat pipe.
